You probably updated from an older 5.x to 5.3? This is libpthread's
obscure way of saying "there are two threads libraries linked to this
app and I can't handle it". Run "ldd -a" on your binary and see if
libc_r got pulled in via a shared library. If so, rebuild that library
so it pulls in libpthread instead of libc_r. A workaround until you
get everything rebuilt is to redirect libc_r to libpthread via
/etc/libmap.conf:
libc_r.so.5 libpthread.so.1
libc_r.so libpthread.so
